Folinic Acid Enhanced Cytotoxicity of Fluoropyrimidines In Human Breast Cancer Cells
Pteridines, 1993 This report describes the effects of the natural diastereoisomer of 5-formyltetrahydrofolate (6S)- and of the mixture of both the natural and unnatural diastereoisomers (6RS)-5-HCO-H4PteGlu (folinate) on the cytotoxicity of 5-fluoro-2′-deoxyuridine ...

Fine structural detection of calcium ions by photoconversion
European Journal of Histochemistry, 2016 We propose a tool for a rapid high-resolution detection of calcium ions which can be used in parallel with other techniques. We have applied a new approach by photo-oxidation of diaminobenzidine in presence of the emission of an excited fluorochrome ...

2-oxoglutarate modulates the affinity of FurA for the ntcA promoter in Anabaena sp. PCC 7120 [PDF]
, 2019 2-oxoglutarate (2-OG) is a central metabolite that acts as a signaling molecule informing about the status of the carbon/nitrogen balance of the cell. In recent years, some transcriptional regulators and even two-component systems have been described as ...

Cytosolic Ca2+ measurements by ratiometric fluorescence microscopy in melanoma cells
STAR Protocols, 2021 Summary: Cytosolic Ca2+ levels are maintained at low nanomolar concentrations, and disruption of Ca2+ homeostasis is associated with cell/tissue damage.

Changes of cytosolic Ca2+ interfere with measurements of cytosolic Mg2+ using mag-fura-2
, 1992 In rat pancreatic and submandibular gland acini during exposure to carbachol, changes in the fluorescence emission intensity ratio (R) of acini loaded with mag-fura-2 resemble changes in cytosolic Ca2+ concentration (Ca2+i) in acini loaded with fura-2 ...

Fura‐2 calcium transients in frog skeletal muscle fibres.
The Journal of Physiology, 1988 1. Intact single twitch fibres from frog muscle were mounted at long sarcomere spacing (3.5‐4.2 microns) on an optical bench apparatus for the measurement of absorbance and fluorescence signals following the myoplasmic injection of either or both of the Ca2+ indicator dyes Fura‐2 and Antipyrylazo III.
